Prosecutors have handled just 19 legacy case files, more than half involving the military, since a new police unit was set up six years ago, the Belfast Telegraph can reveal.
Only five cases out of an overall total of 953 involving 1,184 deaths are currently being probed by the PSNI's Legacy Investigation Branch (LIB), while nine are "under review".
Nine people have been charged since January 2015 - six former members of the Army, two republicans and a single loyalist, currently on trial. There have been no convictions since the cases were transferred to the unit from the Historical Enquiries Team.
"We recognise that the existing system does not satisfy everyone and we would welcome any attempts to better meet the needs of those who lost loved ones," the LIB's head, Detective Chief Superintendent Rowan Moore, said last night.
